What is Causing Bosch Washers To Not Turn On?
The display on a Bosch washer can not turn on at all, or when you go to press the start button nothing happens. There are a range of reasons why this can happen, here’s what they are.
In general, first check that the wall outlet is supplying power to your Bosch washer by plugging in a different device into the wall outlet your Bosch washer is plugged into. Otherwise the following components can have failed, the internal computer, door switch, power cord, or control panel.
When your Bosch washer won’t turn on because the wall outlet is not supplying power, or because the internal computer needs to be restarted you can get it working again yourself. However, for all of the other issues one or more of the components in your Bosch washer will need to be repaired, cleaned, or replaced. Unless you have DIY experience, or appliance repair experience you should have a repair technician do this for you.
In many cases, the repair will be covered under warranty. So, you should enquire first with Bosch if the repair is covered under warranty. Here are each of the reasons why a Bosch washer won’t turn on, why this happens, and how to fix it.
Bosch Washer Won’t Turn On Because It’s Not Getting Power
As you may be aware, there is a main control panel that has fuses for each of the different areas of your home. When there is a power surge, or an area of the house draws too much power the fuse at the control panel will click into the off position. And none of the wall outlets will supply power.
Therefore, you should first check if the wall outlet is supplying power. You can do that by taking another device like a smartphone charger, and a smartphone and plug it into the same wall outlet. This will tell you if the wall outlet is supplying power.
If it isn’t then go to the control board for your home and inspect the fuses. If the fuse to that part of your home is in the off position switch it back into the on position.
Bosch Washer Won’t Turn On Because The Internal Computer has Failed
Bosch washers have an internal computer that provides instructions to the different components. Such as, when to go from a wash cycle to the drain cycle. This internal computer can be frozen and needs to be reset.

Or, it can have blown completely and needs to be replaced. To restart the internal computer unplug your Bosch washer at the wall, wait for about 10 seconds, then plug it back. See if your Bosch washer now starts.
If not this repair needs to be done by a repair technician. So, you should contact Bosch support to see if it’s covered under the manufacturer’s warranty. They can also advise how to have a repair person repair your washer for you.
Bosch Washer Won’t Turn On Because The Door Switch is Faulty
There is a door switch on both front loading and top loading Bosch washers. When the door is closed the onboard computer on a Bosch washer detects that it is. It will then allow the Bosch washer to operate.
If you press the start button for your Bosch washer and it won’t start, then this is a common issue that causes it. Try opening the door, and closing it firmly. You can also try moving the lid slightly to see if it makes a difference.
If you do so it definitely indicates the door switch is faulty, and will need to be repaired or replaced. The door switch needs to be tested and replaced by a repair technician. The best thing to do is contact Bosch support to have a repair technician test and replace it.
Bosch Washer Won’t Turn On Because The Power Cord Is Faulty
Bosch washers have a power cord that can be disconnected from the washer by opening up a few of the panels. The power cord can fail, and needs to be replaced. When it’s faulty it won’t supply power to your Bosch washer, and your Bosch washer won’t turn on.
The power cord like the door switch, and internal computer need to be tested and replaced by a repair technician. So, contact Bosch support if you suspect this is the issue.
Bosch Washer Won’t Turn On Because The Control Board is Faulty
The control board is the part of a Bosch washer where you press the buttons. You can tell it has an issue if some of the buttons work, but others don’t work. There can be a power surge and a part of the control board can be damaged.
If you physically remove the control board you can see areas of it that have burn marks. When the control board is faulty the entire component needs to be replaced. It’s quite difficult to do it yourself if you’ve never done it before and don’t have any experience repairing appliances.
It can also be covered by the warranty. So, you should get in touch with Bosch support to see if it’s covered by warranty. They can also advise how to get a registered repair technician to repair or replace it.
